Titre : From data processing to value creation: understanding professional practices of open data reusers Auteurs : Valentyna Dymytrova, Françoise Paquienséguy, Revue : From Data to Decision Numéro : Issue 1 Volume : 3 Date : 2020/08/5 DOI : ISSN : Résumé : Based on a field survey conducted in France in 2017, this article identifies different forms of open data reuse and analyses the processing data chains on which they are relied. By analysing the chains and the tools used by three categories of professional reusers (developers, data scientists and data journalists), the authors discuss their links with the value creation chain. Professional practices and expectations are also discussed in terms of value generated by data, of economic model (informational brokerage) but also of innovative service creation. This article results partially of the research ANR OpenSensingCity. Éditeur : ISTE OpenScience
